Abstract: An acoustic wave resonator device comprises a substrate carrying a pair of spaced apart reflectors forming a resonant cavity that supports only three adjacent distinct resonant mode frequencies. An interdigital transducer is disposed on the substrate between the reflectors and includes an array of electrodes symmetrically arranged relative to a central point of the cavity to form a plurality of electrode pairs with the electrodes of each pair equally spaced on opposite sides of the central point. The central point of the cavity coincides with a node or an anti-node of the standing wave. If the two electrodes of each electrode pair are connected to the same terminal then the transducer has zero net coupling with one set of alternate modes of the cavity, whereas if said two electrodes are connected to opposite terminals then the transducer has zero net coupling with the other set of alternate modes.

Abstract: An automatic welding apparatus including a robot which comprises a base, a rotary support rotatably mounted on the base, a pair of first arms pivotally movable together and rotatably supported each at its one end by the rotary support, a second arm rotatably supported by the other ends of the first arms at an intermediate portion close to its one end, and a hand connected to the other end of the second arm and rotatable about two axes intersecting each other at right angles. A core wire is supplied from a feeder to a welding torch attached to the hand of the robot. A control device controls movement of the robot, operation of the core wire feeder and power supply to the welding torch. When the forward end of the welding torch comes into contact with the work to be welded, with the core wire drawn into the torch, the resulting short-circuiting is detected to detect the position of the work. The amount of the core wire to be projected from the torch is controlled with reference to the position of the work thus detected.

Abstract: This is a control method for large scale batch reduction of zirconium tetrachloride to zirconium metal. Solid zirconium tetrachloride is fed at least periodically into a sublimer and the sublimer heated to vaporize the zirconium tetrachloride. The vaporized zirconium tetrachloride is fed from the sublimer to a reduction vessel and a measurement is made indicative of this feed (e.g., the flow rate or the pressure in the reduction vessel). A condenser is used to conjunction with said sublimer and the temperature of the condenser is controlled to control the feed of the vaporized zirconium tetrachloride. Preferably, a flow restriction is used between the sublimer and the condenser to provide improved control.

Abstract: A method of reducing the susceptibility to interference of the measured value from a measuring instrument. The measuring instrument is of such a type where a test object is subjected to measurements with respect to a plurality of primary test object properties. Before the actual measurement, the effect has been mapped, by a calibration procedure, which these properties have on the measured value regarding a secondary property of the test object. The calibration procedure is effected on the one hand in that measurements by means of the same or similar instruments are carried out on a sufficient number of test objects each having a known value of the secondary property, and with a sufficient variation of the other test object properties affecting the secondary property, so as to cover expected variations of said properties, and, on the other hand, in that the thus obtained measured values of the primary properties are processed mathematically in such manner that a number of calibration constants in a mathematical relationship between the primary properties and the secondary property are generated. During the calibration procedure, a variation of one or several properties of the measuring instrument, or of representations thereof in the processing of the measured values, is introduced intentionally, said variation having the same order of magnitude as or being substantially greater than expected variations, when one or several test objects are being measured, without such information being supplied to the instrument.

Abstract: Unbleached pulp is combined with an aqueous alkaline solution while in a state of low consistency (9) to distribute a first amount of alkaline material substantially uniformly throughout the pulp. The consistency of the pulp is then increased (12) to above about 18%, and the high consistency alkali containing pulp is then treated with oxygen (21) to effect delignification (20). Additional alkali may be applied onto the high consistency pulp prior to oxygen delignification to provide a total amount of between 0.8 and 7% by weight of oven dry pulp. The invention contemplates the use of one or more wash presses (7,30) for reducing the overall amounts of alkaline material utilized in the process. High strength, low lignin pulps (25) are subsequently formed which may be further bleached to high brightness with reduced amounts of chemicals by following the methods of the invention. <IMAGE>

Abstract: The present invention relates to the activation and deactivation of a transistor (Q1) in a final stage (10), for instance a push-pull final stage. The final stage is included in a voltage alternating drive system connected to a load. A current driving buffer circuit (24) in the drive system is connected to the transistor (Q1) and functions to activate and deactivate the transistor, i.e. to switch the transistor on and off, in a manner such as to generate only a low power loss in the transistor, even when the load is inductive. The current driving buffer circuit (24) includes a first inverting circuit (Q3, Q4), a second inverting circuit (Q5, Q6), a current generating circuit (Q7, Q8), and a semiconductor element (Q9). The inverting circuits coact with the current generating circuit (Q7, Q8) to switch off the transistor (Q1), wherein the current generating circuit generates a deactivation current (IDIS) which charges capacitances (CGSQ1, CGDQ1) in the transistor (Q1) very rapidly, so that the voltage (OUTLSB) on an input of the transistor (Q1) will increase to a deactivation level (VCCH). The inverting circuits coact with the semiconductor element (Q9) to activate or switch on the transistor (Q1), wherewith the semiconductor element generates an activation current (ICON) which charges the capacitances (CGSQ1, CGDQ1) in the transistor (Q1), so that the voltage (OUTLSB) on an input of the transistor (Q1) falls to an activation level (VREG).
